Hello Optera
Love the mod, but i have one gripe with it: The bots still get in the way if i try to mine stuff while they are flitting about.
After a bit of mucking around i managed to fix this by adding

  entity.selection_box = {{ 0, 0}, {0, 0}}

to your data-final-fixes.lua for each bot type.
I'm writing this in case you wish to add it to your official Version.

Thanks for letting me know.
I always thought 0 sized selection boxes where invalid and never tried.

Edit:
This tweak has a potentially annoying side effect. Bots who get lost and just hover in place cant be shot down by most weapons anymore.
I still think it's wort to add.

Finally I found this annoying (non-)bug: the "nonexistent" selection box also makes construction bots not show their cargo anymore (and I like to see what my bots are building) and you cannot check their stats by hovering (I know, it's hard to get a read anyway, since you have to follow them with the mouse while looking for the info box :D)

Click-through bots are a separate startup setting for 0.2.2.
After some testing I default to turning this back off. Having invulnerable bots is too much of a cheat.
